Abstract: In one aspect, a garage door opener system includes a battery configured to be charged by a power source, a controller coupled to the battery, the controller configured to operate a motor that is powered only by the battery, at least one sensor coupled to the motor and the controller, the at least one sensor generating sensor data, and a battery monitoring system coupled to the battery, the controller, and the least one sensor, the battery monitoring system configured to monitor a power consumption of the battery and a state of the battery, and to update an operation configuration of the controller based on historical power consumption of the battery, the state of the battery, and the sensor data.

Abstract: A method of powering an obstruction detector. Power is provided to an obstruction detector when a motor is executing a first movement and is suppressed to the obstruction detector when the motor is idle and when the motor is executing a second movement. The first movement moves a movable barrier towards a closed position, and the second movement moves the barrier towards an open position.

Abstract: A central vacuum power unit includes separate components that can be disassembled and nested together for compact shipment and storage. In the disassembled and nested assembly, the motor module is nested within the dust bucket, and the dust bucket is nested within the body module. For vacuuming operation, the dust bucket is attached below the body module and the motor module is stacked and attached above the body module. A filter is disposed inside the body module and filters debris from air entering the power unit. Debris is collected in the dust bucket, and filtered air is exhausted from a port in the motor module. Latches on the body module are used to attach the dust bucket underneath the body module in operation, and to secure the nested assembly for packaging and shipping.

Abstract: The invention provides a vibration isolation mount for a motorized garage door opener system. The mount includes a substantially planar first mounting plate with apertures configured for mounting to structure inside a garage, and a substantially planar second mounting plate with threaded bolt shafts or other mounting elements configured for mounting to motor mounting structure mounted to a drive motor for use in the system. A vibration isolation material, which may be a natural or synthetic rubber, is disposed between the first and second mounting plates to isolate noise and vibration produced by the motor from the structure mounting the assembly to the interior of the garage.

Abstract: A drive assembly in a motorized door opener includes a motor that is mounted on a mounting structure. At least one vibration isolator is provided between the motor and the mounting structure. The vibration isolator includes a first mounting fastener configured to be mounted to a mounting fastener on the motor, a second mounting fastener configured to be mounted to the mounting structure to mount the motor on the mounting structure, and an elastomeric material between the first and second mounting fasteners. The elastomeric material lies between the first and second mounting fasteners so that the isolator's two mounting fasteners are not in physical contact.
